THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Opening a TAC Case
The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and
P4 cases. (Your network is minimally impaired or you require product information). After you describe
your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution.
If your issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC
engineer.
For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet
access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2
cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447
For a complete listing of Cisco TAC contacts, go to this URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is “down” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Product Overview
Front-Panel Description
10/100 and 10/100/1000 Ports
The Fast Ethernet (10/100-Mbps) and Gigabit Ethernet (10/100/1000-Mbps) ports use standard RJ-45
connectors and Ethernet pinouts with internal crossovers. The maximum cable length is 328 feet (100
meters). 100BASE-TX and 1000BASE-T traffic requires twisted four-pair Category 5 cable. 10BASE-T
traffic can use Category 3 or Category 4 cable.
Fast Ethernet ports operate at 10 or 100 Mbps in either full- or half-duplex mode. In full-duplex mode,
two stations can send and receive traffic at the same time. Normally, 10-Mbps ports operate in
half-duplex mode, which means that stations can either receive or send traffic.
You can configure interface speed on Fast Ethernet and Gigabit Ethernet ports. On Fast Ethernet ports,
you can configure the duplex mode to full, half, or autonegotiate. On Gigabit Ethernet ports, you can
configure ports to full-duplex mode or to autonegotiate; half-duplex mode is not supported.
The default setting is autonegotiate. At this setting, the port senses the speed and duplex settings of the
attached device and advertises its own capabilities. If the connected device also supports
autonegotiation, the switch port negotiates the best connection (that is, the fastest line speed that both
devices support and full-duplex transmission if the attached device supports it) and configures itself
accordingly.
10/100 Inline Power Ports
The 10/100 ports on the Catalyst 3550-24PWR switch provide protocol support for Cisco IP Phones and
Cisco Aironet Access Points:
•
Provide –48 VDC power to all Cisco IP Phones and Cisco Aironet Access Points
•
Automatically detect a Cisco IP Phone or an access point that is connected
On a per-port basis, you can control whether or not a Catalyst 3550-24PWR 10/100 port automatically
provides power when an IP phone or an access point is connected. There are two inline power settings
for each 10/100 port: Auto and Never. When you select the Auto setting for inline power on a port, the
port only provides power if an IP phone or an access point is connected to it. The Auto setting is the
default. However, when you select the Never setting for inline power on a port, the port does not provide
power even if a Cisco IP phone or an access point is connected to it.
100BASE-FX Ports
The 100BASE-FX ports use 50/125- or 62.5/125-micron multimode fiber-optic cabling. In full-duplex
mode, the cable length from a switch to an attached device cannot exceed 6,562 feet (2 kilometers).
The 100BASE-FX ports operate only at 100 Mbps in either full- or half-duplex mode and do not support
autonegotiation. The half-duplex mode is the default setting.
You can connect a 100BASE-FX port to an SC or ST port on a target device by using one of the MT-RJ
fiber-optic patch cables listed in Table B-1 on page B-2.

Front-Panel Description
GBIC Module Slots
You cannot configure speed or duplex mode on GBIC slots, but for certain types of GBICs, you can
configure speed to not negotiate (nonegotiate) if connected to a device that does not support
autonegotiation.
The GBIC module slots support these modules to provide flexibility in media and distance options:
•
1000BASE-T GBIC module for copper connections of up to 328 feet (100 meters).
•
1000BASE-SX GBIC module for fiber-optic connections of up to 1,804 feet (550 meters)
multimode only.
•
1000BASE-LX/LH GBIC module for fiber-optic connections of up to 32,810 feet (10 kilometers)
single mode or 1,804 feet (550 meters) multimode.
•
1000BASE-ZX GBIC module for fiber-optic connections of up to 328,000 feet (100 kilometers)
single mode only.
•
GigaStack GBIC module for creating a 1-Gbps stack configuration of up to nine supported switches.
The GigaStack GBIC supports one full-duplex link (in a point-to-point configuration) or up to nine
half-duplex links (in a stack configuration) to other Gigabit Ethernet devices. When you use the
required Cisco proprietary signaling and cabling, the maximum distance for a GigaStack
GBIC-to-GigaStack GBIC connection is 3 feet (1 meter).
•
Coarse Wave Division Multiplexing (CWDM) GBIC modules for fiber-optic connections of up to
393,719 feet (120 kilometers) single mode only.
Cisco-approved CWDM GBIC modules have a serial EEPROM that contains the module serial
number, the vendor name and vendor ID, a unique security code, and cyclic redundancy check
(CRC). When a CWDM GBIC module is inserted in the switch, the switch software reads the
EEPROM to check the serial number, vendor name and vendor ID, and recompute the security code
and CRC. If the serial number, the vendor name or vendor ID, the security code, or CRC is invalid,
the switch places the port in an error-disabled state.
For more information about GBICs, see the documentation included with your GBIC module and
Related Publications, page xiii, for a list of related documentation.
LEDs
You can use the switch LEDs to monitor switch activity and its performance. Figure 1-3 shows the LEDs
and the Mode button that you use to select one of the port modes.
All of the LEDs described in this section except the utilization meter (UTIL) are visible on the device
manager and through the Network Assistant.

For more information about the Cisco RPS 300 or the Cisco RPS 675, see the documentation included
with the RPS.
Port LEDs and Modes
Each RJ-45 port and GBIC module slot has a port LED. These port LEDs, as a group or individually,
display information about the switch and about the individual ports. The port mode determines the type
of information displayed through the port LEDs. Table 1-4 lists the mode LEDs and their associated port
modes and meanings.
To select or change a mode, press the Mode button (or Mode label on the Catalyst 3550-48 switch) until
the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also
change. Table 1-5 explains how to interpret the port LED colors in different port modes.
You can also use the Mode button to activate the Express Setup program or to clear the switch IP address
and all switch settings. See the “Clearing the Switch IP Address and Configuration” section on page 3-1
for more information.

Management Options
AC Power Connector
For AC-powered switches, the internal power supply is an autoranging unit that supports input voltages
between 100 and 240 VAC.
For the Catalyst 2440-24-DC power information, see Appendix C, “DC Power Connections.”
Cisco RPS Connector
For protection against a power supply failure, you can connect a Cisco RPS to the switch. The Cisco RPS
can support six external network devices and provide power to one failed device at a time. It
automatically senses when the internal power supply of a connected device fails and provides power to
the failed device, preventing loss of network traffic.
The Cisco RPS 300 has two output levels: –48 V and 12 V with a total maximum output power of 300 W.
The Cisco RPS 675 has two output levels: –48 V and 12 V with a total maximum output power of 675 W.
These Cisco RPS models support the Catalyst 3550 switches:
•
Cisco RPS 300 (model PWR300-AC-RPS-N1) supports the
Catalyst 3550-12T, 3550-12G, 3550-24, 3550-FX, and 3550-48 switches.
•
Cisco RPS 675 (model PWR675-AC-RPS-N1) supports the
Catalyst 3550-12T, 3550-12G, 3550-24, 3550-FX, 3550-24PWR, and 3550-48 switches.
The Cisco RPS 300 does not support the Catalyst 3550-24-DC or 3550-24PWR switch. The Cisco RPS
675 does not support the Catalyst 3550-24-DC switch.
The RPS 300 and RPS 675 models also support other Cisco devices. See the RPS documentation for
more information.
Console Port
You can connect the switch to a PC by using the console port and the supplied RJ-45-to-DB-9 adapter
cable. If you want to connect the switch console port to a terminal, you need to provide an
RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing
that adapter from Cisco.
Management Options
The Catalyst 3550 switches offer several management options:
•
Network Assistant
•
The Network Assistant is a GUI-based application that you can install and run on your desktop; you
do not need a web browser to run it. You can use Network Assistant to manage and monitor switch
clusters or standalone devices. For more information, see the Getting Started with Cisco Network
Assistant guide and the Network Assistant online help.
Catalyst 3550 Switch Hardware Installation Guide
OL-6155-01
1-11
Chapter 1
Product Overview
Management Options
•
Device manager
You can use the device manager, which is in the switch memory, to manage individual and
standalone switches. The device manager is accessible after you have run the Express Setup program
(see the getting started guide for more information about running Express Setup). Use the device
manager to perform basic switch configuration and monitoring. You can access the device manager
from anywhere in your network through a web browser.
To launch the device manager, enter the switch IP address in the web browser, and press Enter.
The device manager page appears.
See the device manager online help for more information.
•
Cisco IOS command-line interface (CLI)
The switch CLI is based on Cisco IOS software and is enhanced to support desktop-switching
features. You can fully configure and monitor the switch and switch cluster members from the CLI.
You can access the CLI either by connecting your management station directly to the switch console
port or by using Telnet from a remote management station. See the command reference on
Cisco.com for more information.
•
SmartPort Macros
SmartPort macros provide a convenient way to save and share common switch configurations. You
can use SmartPort macros to enable features and settings based on the location of a switch in the
network and for mass configuration deployments across the network.
Cisco provides a collection of pretested, Cisco-recommended baseline SmartPort macros for
Catalyst switches. You can use the macros to build and deploy Cisco-recommended network designs
and configurations. For more information about SmartPort macros, see the software configuration
guide and the SmartPort information available on Cisco.com.
•
CiscoView application
The CiscoView device-management application displays the switch image that you can use to set
configuration parameters and to view switch status and performance information. The CiscoView
application, which you purchase separately, can be a standalone application or part of an SNMP
platform. See the CiscoView documentation for more information.

Switch Installation
Powering the Switch and Connecting Devices
The switch 10/100 and 10/100/1000 port default setting is autonegotiate. If the attached device does not
support autonegotiation, you can explicitly set the speed and duplex parameters. After connecting the
cable, the port LED turns green when both the switch and the connected device have established a link.
Connecting to the 10/100 Inline Power Ports
You can connect the Catalyst 3550-24PWR switch to a Cisco IP Phone through a straight-through,
twisted four-pair Category 5 cable. The rear panel of the Cisco IP Phone might have more than one RJ-45
connector. Use the LAN-to-phone connector to connect the IP phone to the Catalyst 3550-24PWR
switch.
You can configure the 10/100 ports on the Catalyst 3550-24PWR switch to either automatically provide
inline power when a Cisco IP Phone or a Cisco Aironet Access Point is connected or to never provide
inline power even if an IP phone or an access point is connected. The default setting is Auto.
Warning
Voltages that present a shock hazard can exist on inline power circuits if interconnections are made
by using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such
interconnection methods unless the exposed metal parts are in a restricted access location and users
and service people who are authorized to access the location are made aware of the hazard. A
restricted access area can be accessed only through the use of a special tool, lock and key, or other
means of security. Statement 1072
Caution
It takes a Catalyst 3550-24PWR 10/100 port up to 10 seconds to initially detect, power up, and link to a
Cisco IP Phone. If you disconnect the Cisco IP Phone before link is established, you must wait 10
seconds before connecting another network device (other than another IP phone) to that switch port.
Failure to do so can result in damage to that network device.
You also can connect the Cisco IP Phone or Cisco Aironet Access Point to a Catalyst 3550-24PWR
10/100 port and to an AC power source for redundant power. The power source to which the external
device is first connected becomes its primary power source, and the second power source is its backup.
If the primary source fails, the second power source becomes the primary power source to the device.
During the power transfer, the device might reboot or reestablish link with the switch.
For information about Cisco IP Phones and Cisco Aironet Access Points, see the documentation that
came with your IP phone or access point.
Connecting to 100BASE-FX Ports
Caution
To prevent ESD damage, follow your normal board and component handling procedures when
connecting to the 100BASE-FX ports.
The 100BASE-FX ports operate only at 100 Mbps and support both full- and half-duplex mode. The
half-duplex mode is the default setting. Autonegotiation is not supported.
To connect to a 100BASE-FX port, remove the rubber plug from the port and the rubber cap from the
MT-RJ patch cable. Store for future use. Insert the cable in the port, and insert the other cable end in an
SC or ST connector on the target device. The port LED turns green when both the switch and the
connected device have established a link.

Caution
Do not remove the rubber plugs from the fiber-optic ports or the rubber caps from the fiber-optic cable
until you are ready to connect the cable. The plugs and caps protect the fiber-optic ports and cables from
contamination and ambient light.
You can connect a 100BASE-FX port to an SC or ST connector on a compatible device by using one of
the MT-RJ fiber-optic patch cables listed in Table B-1 on page B-2.

Troubleshooting
This chapter describes these troubleshooting topics:
•
Understanding POST Results, page 3-1
•
Clearing the Switch IP Address and Configuration, page 3-1
•
Diagnosing Problems, page 3-2
Understanding POST Results
While the switch powers on, it automatically begins POST, a series of tests that verifies that the switch
functions properly. POST lasts approximately 1 minute. When the switch begins POST, the port LEDs
turn green, the system LED blinks green, the RPS LED turns off, and then the first two port LEDs turn
off. When POST completes, the port LEDs return to the status mode display, and the system LED is
green. If POST fails, the system LED is amber, and the port LED associated with the test is amber.
If POST fails, the SYST LED turns amber. Table 3-1 on page 3-3 lists causes and resolutions for a POST
failure. POST failures are usually fatal. Contact your Cisco representative if your switch does not pass
POST.
Note
The LEDs on a Catalyst 3550-24PWR switch function differently during POST. Use the console port to
view the POST results.
Clearing the Switch IP Address and Configuration
If you have configured a new switch with a wrong IP address, or if all the switch LEDs start blinking
when you are trying to enter Express Setup mode, you can clear the IP address that is configured on
the switch.
Note
This procedure clears the IP address and all configuration information stored on the switch. Do not
follow this procedure unless you want to completely reconfigure the switch.
To clear the IP address and the switch configuration information, follow these steps:
Step 1
Press and hold the Mode button.
Catalyst 3550 Switch Hardware Installation Guide
OL-6155-01

Chapter 3
Troubleshooting
Diagnosing Problems
The switch LEDs begin blinking after about 2 seconds.
Note
Step 2
If the switch is not configured, the LEDs are all green. You can omit Step 2 and run Express
Setup to configure the switch.
Continue holding down the Mode button. The LEDs stop blinking after 8 additional seconds, and then
the switch reboots.
The switch now behaves like an unconfigured switch. You can configure the switch by using Express
Setup as described in the getting started guide. You can also configure the switch by using the
command-line interface (CLI) setup procedure described in Appendix D, “Configuring the Switch with
the CLI-Based Setup Program.”
Diagnosing Problems
The LEDs on the front panel provide troubleshooting information about the switch. They show POST
failures, port-connectivity problems, and overall switch performance. For a full description of the switch
LEDs, see the “LEDs” section on page 1-6.
You can also get statistics from the browser interface, from the CLI, or from an SNMP workstation.
See the software configuration guide and the switch command reference guide on Cisco.com or the
documentation that came with your SNMP application for details.

errors
Solution
•
Verify that the devices at both ends of the link are connected
and powered.
•
Verify that the autonegotiation settings are the same at both
ends.
•
Verify that you are using the appropriate Ethernet cable for the
connected device. See Table 2-1 on page 2-17 for cabling
requirements.
•
Verify that the cable is good by testing it on another device.
Replace it with a known working cable.
•
STP might be checking for possible loops. Wait 30 seconds for
the port LED to turn green.
•
For 1000BASE-T connections, make sure to use a twisted
four-pair, Category 5 cable.
•
The switch is not recognizing a GBIC module. See the “GBIC
Module Slots” section on page 1-6 for Cisco-recommended
GBIC modules, and see your GBIC module documentation for
more information.
•
There might be a speed and duplex autonegotiation mismatch.
Use the show controllers ethernet-controller privileged
EXEC command to display per-port send and receive statistics
read from the hardware. You can also use the show interfaces
privileged EXEC command to display the administrative and
operational status of all ports or a specified port.
•
The cabling distance might be exceeded. Reduce the cable
length to within the distances listed in the “Front-Panel
Description” section on page 1-4.

Configuring the Switch with the CLI-Based
Setup Program
This appendix provides a command-line interface (CLI)-based setup procedure for a standalone switch.
Before connecting the switch to a power source, review the safety warnings in Chapter 2, “Switch
Installation.”
For an unconfigured switch, you can access the CLI either through Express Setup or through the console
port. These sections describe each method:
•
Accessing the CLI Through Express Setup, page D-1
•
Accessing the CLI Through the Console Port, page D-2
Accessing the CLI Through Express Setup
Express Setup is supported on switches running Cisco IOS Release 12.1(14)EA1 or later. If you are
installing an unconfigured switch, see the Cisco IOS release label on the rear panel of the switch to
determine the software release.
Note
For switches running releases earlier than Cisco IOS Release 12.1(14)EA1, go to the “Accessing the CLI
Through the Console Port” section on page D-2.
You can access the CLI on an unconfigured switch by placing the switch in Express Setup mode and then
by connecting a switch Ethernet port to the Ethernet port of your PC or workstation. To put the switch
into Express Setup mode, follow the steps described in the getting started guide for powering on the
switch and using Express Setup.
After the switch is in Express Setup mode, open a Telnet session to the switch by entering the IP address
10.0.0.1. Enter the setup user EXEC command. See these sections in this chapter to then configure the
switch by using the CLI:
•
Entering the Initial Configuration Information, page D-4
•
Completing the Setup Program, page D-5
After you have entered the configuration information for the switch, save it to Flash memory by using
the write memory privileged EXEC command.
Catalyst 3550 Multilayer Switch Hardware Installation Guide
OL-6155-01
D-1
Appendix D
Configuring the Switch with the CLI-Based Setup Program
Accessing the CLI Through the Console Port
Note
While in Express Setup mode, the IP address 10.0.0.1 is active until you enter the write memory
command. You lose the Telnet connection after entering the write memory command.
For more information about using the CLI, see the switch command reference for this release.
Accessing the CLI Through the Console Port
You can access the CLI on a configured or unconfigured switch by connecting the console port of the
switch to the serial port on your PC or workstation and accessing the switch through a
terminal-emulation session. To access the switch through the console port, follow these steps:
•
“Connecting to the Console Port” section on page D-2
•
“Starting the Terminal-Emulation Software” section on page D-3
•
“Powering on the Switch” section on page D-4
Connecting to the Console Port
Follow these steps to connect the PC or terminal to the switch console port:
Step 1
Using the supplied RJ-45-to-DB-9 adapter cable, insert the RJ-45 connector into the console port on the
rear of the switch, as shown in Figure D-1.
Step 2
Attach the DB-9 female DTE of the adapter cable to the PC serial port, or attach an appropriate adapter
to the terminal.

Starting the Terminal-Emulation Software
Before you power on the switch, start the terminal emulation session so that you can see the output
display from the power-on self-test (POST).
The terminal-emulation software—frequently a PC application such as Hyperterminal or
ProcommPlus—makes communication between the switch and your PC or terminal possible.
Follow these steps to start a terminal-emulation session:
Step 1
Start the terminal-emulation program if you are using a PC or terminal.
Step 2
Configure the baud rate and character format of the PC or terminal to match these console port default
characteristics:
•
9600 baud
•
8 data bits
•
1 stop bit
•
No parity
•
None (flow control)

Appendix D
Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
Powering on the Switch
Complete these steps to power on the switch:
Step 1
Connect one end of the supplied AC power cord to the power connector on the switch rear panel. See
Figure D-1.
Step 2
Connect the other end of the power cable to a grounded AC outlet.
As the switch powers on, it begins POST, a series of tests that run automatically to ensure that the switch
functions properly. If POST fails, see the “Understanding POST Results” section on page 3-1 to
determine a course of action.
If you started the terminal emulation program before you powered on your switch, the PC or terminal
displays the bootloader sequence. You need to press Enter to display the setup program prompt. See
these sections to then configure the switch by using the CLI:
•
Entering the Initial Configuration Information, page D-4
•
Completing the Setup Program, page D-5
Entering the Initial Configuration Information
To set up the switch, you must assign an IP address and other configuration information necessary for
the switch to communicate with the local routers and the Internet. This information is also required if
you plan to use the Network Assistant to configure and manage the switch.
IP Settings
You will need this information from your network administrator before you complete the setup program:
•
Switch IP address
•
Subnet mask (IP netmask)
•
Default gateway (router)
•
Enable secret password
•
